Atorvastatin Impurity RRT 1.58 (INR 54900/-, 50 mg, in stock)

Atorvastatin Impurity RRT 1.58 is a pharmaceutical impurity reference standard supplied by Allas Chem Tech, related to Atorvastatin. It is intended for use in analytical method validation (AMV) and routine quality control (QC) testing of Atorvastatin drug substance and drug product batches.

About This Impurity Standard

Atorvastatin Impurity RRT 1.58 is characterised and supplied as a 50 mg reference standard pack, priced at Rs.54900/- and currently shown as In Stock on the product listing. STRONG FLAG: "RRT 1.58" is a Relative Retention Time designation (a chromatographic identifier tied to a specific validated HPLC method), not a common/pharmacopoeial impurity name, and no source consulted (Veeprho, Simson Pharma, GLP Pharma Standards — whose full approx. 31-entry Atorvastatin impurity table was checked in full, Chemicea, SynZeal) lists any Atorvastatin impurity under this RRT value. A coincidentally similarly-numbered "Atorvastatin Impurity 158" was found on Veeprho but ruled out as an unrelated catalog-numbering match, not a genuine RRT match (different structure, a sodium-salt degradation product, no RRT reference in its own listing). CAS/formula/structure left entirely blank — publishing a specific chemical identity here without a sourced structure would be unsupported speculation. This is the highest-priced row in the whole job to date (Rs.54900); recommend the client's own QC/analytical department or original method source identify the actual compound behind this RRT value before any structural claims are published.

Specifications

Analytical Applications

General Use

This reference standard supports impurity profiling, forced-degradation studies, and stability-indicating HPLC/UPLC method development and validation for Atorvastatin-based formulations, in line with ICH Q3A/Q3B impurity qualification requirements.

Compound-Specific Notes

HIGH-PRIORITY STRONG FLAG: "RRT 1.58" is a method-relative chromatographic identifier, not a registered/named impurity in any of the approx. 10 third-party sources checked — no CAS/formula/MW found anywhere. Highest-priced row in the job to date (Rs.54900).

Quality Control

Use of a well-characterized Atorvastatin Impurity RRT 1.58 reference standard supports accurate peak identification and quantitation during routine QC release testing and stability studies for Atorvastatin drug substance and finished-dose batches.

Documentation Supplied

Each unit of Atorvastatin Impurity RRT 1.58 ships with a Certificate of Analysis (CoA), Material Safety Data Sheet (MSDS), and supporting HPLC chromatographic/analytical data confirming the stated identity and purity.

Synonyms and Alternate Designations
