Chemical Structure

Fosfomycin Trometamol EP Impurity B TEA Salt CAS 1262243-11-7(free base) chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Fosfomycin Trometamol EP Impurity B TEA Salt.

Fosfomycin Trometamol EP Impurity B TEA Salt (CAS 1262243-11-7(free base)) is a certified pharmaceutical impurity reference standard with the molecular formula C7H18NO7PC6H15N and a molecular weight of 360.39 g/mol.

Owing to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Fosfomycin Trometamol EP Impurity B TEA Salt is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 360.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 Fosfomycin Trometamol EP Impurity B TEA Salt 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.
