Chemical Structure

Bromhexine Impurity 13 CAS 1660957-96-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 368.14 g/mol gives Bromhexine Impurity 13 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Bromhexine Impurity 13 (CAS 1660957-96-9) is a certified pharmaceutical impurity reference standard with the molecular formula C14H20BrClN2HCl and a molecular weight of 368.14 g/mol.

Structurally, Bromhexine Impurity 13 (C14H20BrClN2HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 368.14 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 Bromhexine Impurity 13 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.
