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 Phosphocholine (chloride disodium).
Phosphocholine (chloride disodium) (CAS 16904-96-4) is a high-purity analytical reference standard with the molecular formula C5H13NNa2O4PCl and a molecular weight of 263.57 g/mol.
Owing to a salt form, a carbohydrate-derived structure, an amide group, a phosphate ester group, chlorine substitution, Phosphocholine (chloride disodium) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 263.57 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 analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Phosphocholine (chloride disodium) 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.
