Abscisic Acid CAS 21293-29-8

1. Abscisic acid is a naturally occurring plant hormone primarily used in agricultural research to regulate plant growth, dormancy, stomatal closure, and stress responses to drought, salinity, and cold .
2. Abscisic acid CAS 21293-29-8 serves as a key research tool for studying abscisic acid signaling pathways, including the core PYR/PYL receptor, PP2C phosphatase, and SnRK2 kinase cascade, which are critical for understanding plant adaptation to environmental stress .
3. Abscisic acid is employed in horticultural applications to improve fruit ripening control, reduce transpiration in nursery plants during transport, and enhance drought tolerance in crops through exogenous application .
4. Researchers utilize Abscisic acid CAS 21293-29-8 in plant physiology, molecular biology, and genetic studies to investigate seed development, germination inhibition, and the cross-talk between abscisic acid and other phytohormones .

1. Abscisic acid must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment; powder is stable for up to 3 years at -20°C or 2 years at 4°C, protected from light .
2. For solution storage, prepare aliquots in tightly sealed vials and store at -20°C for up to 1 month or at -80°C for up to 6 months; avoid repeated freeze-thaw cycles to prevent degradation .
3. Abscisic acid CAS 21293-29-8 is classified with GHS hazard statements H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation), with signal word "Warning" .
4. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, ensuring adequate ventilation in work areas and avoiding formation of dust and aerosols .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator when Abscisic acid is released .
2. Collect Abscisic acid CAS 21293-29-8 by sweeping or vacuuming without creating dust using non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; prevent the product from entering drains or water courses .
4. Dispose of collected material according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration .

1. Abscisic acid is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide, carbon dioxide, and nitrogen oxides (NOx) .
2. Use water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product; do NOT use a direct water jet as Abscisic acid CAS 21293-29-8 may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning Abscisic acid due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; move containers from the fire area if safe to do so, and contain fire runoff to prevent environmental contamination .
