    5-bromo-1H-pyrazolo[3,4-c]pyridine (929617-35-6) Description

    The product is a pharmaceutical intermediate with an inhibiting effect against the epidermal growth factor receptor (EGFR) mutants.Activatingmutations at L858R position within the EGFR proteinat the kinase domain are responsible for exon 19 deletions.

    Just like the standard therapies like erlotinib and gefitinib,diaminopyrimidine inhibitorsreducetumor progression, thereby, increasing the survival rate.The inhibitory effect makes it a better treatment for non-small cell lung cancers. Mutation occurring at the EGFR protein kinase domain usually involves the substitution of threonine-790 with methionine, which exhibits resistance to erlotinib treatment.

    From an x-ray crystal structure of the inhibitory agents, two unique binding modes are disclosed, giving rise to a scientific design of diaminopyrimidine-based inhibitors. These products tend to be selective over kinases and wild-type EGFR. They also have a high inhibitory factor against T790M, and EGFR mutants.

    Safety measures when dealing with 5-Bromo-1H-pyrazolo(3,4-c)pyridine

    1. Personal Protection

    Wear protective clothing when working with 5-Bromo-1H-pyrazolo(3,4-c)pyridine to minimize the hazards associated with it. For face and eye protection, put on a mask and a respirator with air-purifying capabilities. Use chemical-resistant rubber gloves, safety goggles, and impervious footwear.

    2. Engineering Controls

    Work in a laboratory equipped with adequate exhaust ventilation, a safety shower, a chemical fume hood, and emission source isolation.These features should at least isolate the air contaminants by directing them away from the source.

    3. First Aid Measures


    Breathing the chemical fumes may irritate the throat and cause discomfort in the chest. When this occurs, move the victim in a well-ventilated area or the outdoor space. If there are difficulties in breathing, use a breathing apparatus and seek advice from a professional.

    Skin contact

    Wash the affected area with plenty of running water and mild soap for several minutes. If the irritation persists, seek medical attention.


    Thoroughly wash the mouth or drink up to half liters of water. Contact a poison center for further advice if the casualty experiences persistent oral soreness, nausea, or stomach pains.

    Eye contact

    If you have contact lenses, remove them before flushing the eyes with copious amount of cold water. Seek medical care in case of severe irritation, redness, or watery eyes.
