Herbert Brown Pharmaceutical and Research Laboratories. (HBPRL) has been into manufacturing of Oligonucleotide materials since last 20years. Nobel Laureate, Dr. Herbert Brown himself inaugurated this site in 1984, hence the site name has been dedicated to him
Processes requiring extremely high accuracy and precision controls such as in loading of Solid support (polymeric beads) with oligonucleotide materials is being carried out in HBPRL on a regular basis.
Quality: All the manufacturing activities for Oligonucleotide materials is in GMP conditions with 21 CFR system support. Close Monitoring and control on the impurities as LCMS is used as a part of QC release of batches. Moisture control at ppb levels required for certain products.
Nucleosides are being exported primarily to US and European countries
Over the years HBPRL has developed expertise in making small volume high value products and thus built capabilities in the following aspects
- Storage and transportation at -20℃
- Column chromatography
- Lyophilization
Pilot scale and Plant scale reactors available
APIs and Intermediates for domestic/ international markets
EHS and sustainability: HBPRL has been rated by Ecovadis

Nucleosides: DNA and RNA building blocks
Sulfur Transfer Agent for synthesis of Oligonucleotides
