Calcitriol Impurity 61 CAS CATO-C4X-151061

Description

The occurrence of Calcitriol Impurity 61 is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Calcitriol Impurity 61 (CAS CATO-C4X-151061) is a certified pharmaceutical impurity reference standard with the molecular formula C27H44O2 and a molecular weight of 400.64 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, Calcitriol Impurity 61 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 400.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Calcitriol Impurity 61 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
