Calcipotrieno CAS 112828-00-9

Longchang source page for Calcipotriene / Calcipotriol, source-record CAS 112828-00-9. Because public identifier records are not uniform, send the required name, CAS basis, stereochemistry, hydration state, identity method, target specification and quantity to request current identity confirmation, analytical methods, applicable lot COA, SDS status, sample availability, packaging, MOQ, current availability and confirmed lead time.

Identity fields to confirm

PubChem currently lists 112965-21-6 under CAS, continues to associate 112828-00-9 through an ECHA contribution and labels 112828-00-9 as deprecated in a ChemIDplus contribution. NIH NCATS/GSRS aggregation also associates 112828-00-9 with the Calcipotriene active-moiety record. The current RFQ should resolve the identifier and material basis rather than relying on the URL alone.

Information to request for qualification

Historical source-record fields

The previous page displayed the fields below without a visible current controlled specification number, hydration basis, complete method set, lot identity, effective date or approval status. They are historical sourcing context only. They are not a current Longchang specification, lot result, grade statement, compendial claim or regulatory declaration.

Anhydrous, hydrate and finished-product boundary

En reviewed current DailyMed ointment label states the anhydrous formula C₂₇H₄₀O₃ and molecular weight 412.62. Other DailyMed cream and solution labels describe Calcipotriene monohydrate, C₂₇H₄₀O₃·H₂O, with molecular weight 430.6. A quotation must identify which material basis is offered and how assay is reported.

A DailyMed label belongs to the named finished prescription product. It does not establish that a current Longchang lot is an approved drug, approved dosage form, pharmacopeial grade, equivalent formulation or suitable for a buyer’s market. Patient directions, treatment duration, adverse-event advice and clinical results from a finished label are not raw-material usage instructions.

Application and regulatory boundary

The database category `Api`, an ingredient name, a CAS association or a finished-product label does not by itself establish manufacturing authorization, GMP status, compendial compliance, regulatory filing support or suitability for a buyer’s finished product. Qualification must cover identity and material basis, assay and impurities, process/formulation, safety controls, quality agreements, current destination-market rules and the buyer’s approval requirements.

Safety and handling boundary

This page is not a substitute for an SDS or a site-specific risk assessment. Request the current supplier SDS and use it with local rules and the buyer’s procedures to define classification, receipt, storage, transfer, processing, transport and disposal controls for the material supplied. Finished-product safety and patient information require a separate competent review of the actual formulation and applicable labeling.

Read the identity and label-context guide

Review the Calcipotriene and Calcipotriol identity guide for name equivalence, CAS-source differences, anhydrous versus monohydrate interpretation, the steroid-classification question and the boundary between chemical records and finished-drug labels.
