General description

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Escitalopram Oxalate, a highly selective serotonin re-uptake inhibitor antidepressant, is a pure S-enantiomer of the racemic, bicyclic pthalates derivatives of citalopram. It is mainly developed for the treatment of depression and anxiety disorders.

Application

Escitalopram Oxalate may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using high-performance thin layer chromatography technique and reversed-phase high-performance liquid chromatography technique.
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Biochem/physiol Actions

Escitalopram is a selective serotonin reuptake inhibitor (SSRI), the S-enantiomer and eutomer of citalopram.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.

Other Notes

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
