Steroid-Related Organic Intermediate Candidate — CAS Requires Verification

Buyer-facing sourcing candidate for an organic intermediate advertised for controlled chemical or pharmaceutical manufacturing supply chains. The listing contains conflicting identifiers and specifications, including CAS 1099-08-1 in the title, CAS 2226-96-2 in extracted basic specs, and CAS 7753-60-8 in the product description for 21-Hydroxy-20-methyl-pregn-4-ene-3-one. Overseas buyers should treat this as a documentation-first RFQ item and request confirmation of exact CAS, molecular identity, grade, impurity profile, export eligibility, and batch-specific COA before technical or commercial evaluation.

Identity and grade

Typical specifications

  • Advertised product name: 21-Hydroxy-20-methyl-pregn-4-ene-3-one, subject to supplier confirmation
  • CAS identifiers shown conflict: 1099-08-1, 2226-96-2, and 7753-60-8 all appear in the source material
  • Advertised grade: Industrial / pharma intermediate, to be clarified as non-GMP, GMP, research, pilot, or commercial manufacturing grade
  • Advertised purity: ≥98.0% in product description; ≥99.0% in basic specification section, requires COA confirmation
  • Appearance conflict: Orange to red crystalline solid in extracted specs; white to off-white powder in product description
  • Formula shown as C9H18NO2 in basic specs, which should be checked against the confirmed CAS and structure
  • EINECS shown: 218-760-9, requires verification against confirmed CAS
  • Shelf life shown: 24 months under stated storage conditions, subject to batch COA and stability documentation
  • Availability shown as in stock / made to order, to be confirmed with current batch number and lead time
Who uses this page

Target buyers

  • Qualified chemical distributors with controlled-product screening procedures
  • Pharmaceutical intermediate sourcing teams with internal QA and regulatory review
  • Fine chemical importers requiring batch-level documentation before purchase
  • Contract research or development organizations sourcing documented intermediates for permitted R&D use

Before matching

Documents to check

  • CAS number, grade, assay, and impurity profile
  • SDS, COA, TDS, HS code, and transport classification
  • Destination-market import documents before supplier matching
Package and route

Packing notes

  • Advertised packing: 25 kg fiber drum with inner PE liner
  • Request confirmation of net weight, gross weight, drum dimensions, palletization, and labeling language for export shipments
  • Ask whether smaller qualification packs or retained samples are available for pre-shipment testing
  • Confirm whether packaging is suitable for the confirmed hazard classification and destination-country import requirements
  • Request photos of actual batch packaging and label draft before shipment, not only illustrative product images
Applications and sourcing options

Check whether this product fits the buyer's actual application.

Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.

Use context

Common applications

  • Document-led RFQ evaluation for a steroid-related organic intermediate candidate
  • Supplier prequalification where CAS, grade, impurity profile, and export status must be verified
  • Small-sample qualification followed by independent analytical confirmation
  • Non-clinical, permitted chemical manufacturing supply-chain review subject to buyer compliance approval
  • Comparison of China-origin intermediate suppliers based on COA, SDS, traceability, and export readiness
How we compare

Sourcing options

  • Request a corrected quotation under the confirmed CAS and product name only
  • Ask for a pre-shipment sample and third-party lab verification before bulk procurement
  • Use an escrow or staged payment structure tied to document acceptance and independent testing
  • Require supplier declaration covering manufacturer status, origin, batch traceability, and export compliance
  • Consider alternate suppliers if CAS identity, assay, impurity controls, or transport classification cannot be documented
Human review

Compliance notes

  • Do not rely on the advertised title alone; the CAS and product identity must be reconciled before procurement
  • Because the listing references steroid, hormone, pharma intermediate, and FDA-related terms, buyer should perform enhanced compliance review before RFQ award
  • Request SDS, COA, TDS/specification sheet, impurity statement, residual solvent statement, origin statement, and export documentation draft
  • Confirm whether the material is subject to pharmaceutical, steroid, hormone, controlled-substance, dual-use, customs, or destination-country import restrictions
  • Supplier should confirm HS code, DG classification, UN number if applicable, packing group if applicable, and whether non-DG status is supported by SDS
  • No regulatory approval, FDA status, pharmacopoeial compliance, or import admissibility should be assumed from the listing wording
  • Confirm whether the supplier is the manufacturer or trader and whether manufacturing site documentation is available under NDA
  • For regulated end uses, buyer should obtain legal and QA approval in the destination jurisdiction before purchase
