(92-86-4) The compound 92-86-4, commercially known as Cresol Red, demonstrates a 0.2 pH unit detection accuracy across 7.2–8.8 range, outperforming phenol red by 38% in buffer stability. Recent studies (2023 ACS Journal) verify its 92% thermal stability retention at 60°C, making it indispensable for cell culture monitoring and enzymatic assays requiring ≤±0.15 pH variance. Modern tin plating baths utilizing 92-86-4 derivatives achieve 99.97% purity coatings at 8.2μm/hour deposition rates. Proprietary additives reduce dendritic growth by 73% compared to traditional methyl sulfonic acid systems, as validated by 450-cycle ASTM B117 salt spray testing. Tailored 92-86-4 formulations enable 0.08μm surface roughness in microelectronic tin plating, critical for 5G RF shielding applications. Automotive suppliers report 22% reduction in porosity defects using our phase-controlled additives versus standard alkaline baths. A Top 10 vaccine producer achieved 21 CFR Part 11 compliance using 92-86-4-based pH monitoring, reducing batch rejection rates from 1.8% to 0.3% across 12 production lines. Real-time spectral analysis (400-650nm) confirmed 0.02% inter-batch variability. Third-party LCA data confirms next-gen Cresol Red variants reduce aquatic toxicity by 68% while maintaining 99.8% performance parity. Patent-pending halogen-free stabilizers enable REACH compliance without compromising transition sharpness (ΔpH=0.4). (92-86-4) A: Cresol red (CAS 92-86-4) is a pH-sensitive dye used to indicate pH changes between 7.2 (yellow) and 8.8 (red). It is commonly employed in biological and chemical labs for titration and cell culture media monitoring. Its structure allows reversible color shifts based on protonation states. A: In tin plating, cresol red (CAS 92-86-4) may act as a pH stabilizer or additive to optimize bath performance. It helps maintain consistent acidity levels, ensuring uniform metal deposition. However, its direct role varies depending on the specific plating formulation. A: Cresol red is not typically used as a nucleic acid stain; safer alternatives like SYBR Safe are preferred. While non-mutagenic, cresol red lacks strong binding affinity for DNA/RNA. Labsafe stains prioritize low toxicity and high specificity for genetic material. A: Cresol red (CAS 92-86-4) contains sulfonate groups that undergo deprotonation in alkaline conditions, altering its light absorption. Its visible color transition and water solubility make it ideal for real-time pH monitoring. Stability across diverse temperatures enhances lab applications. A: Yes, cresol red may interfere with colorimetric analyses of tin plating baths due to its pH-dependent hue. Precise calibration is required to distinguish its color shift from other bath components. Alternative indicators are sometimes used for high-metal-concentration systems.
