According to GlobalData’s company profile on Entegris, 3D memory devices was a key innovation area identified from patents. Entegris's grant share as of January 2024 was 50%. Grant share is based on the ratio of number of grants to total number of patents.

The granted patent (Publication Number: US11884606B2) discloses a process for preparing a compound of Formula (I) through specific methods involving protic reagents such as water, alcohol, or polyol. The process includes the use of these reagents in combination with acids to achieve the desired compound. Additionally, the patent specifies the composition requirements for the compound, ensuring it has less than 0.5 weight percent of multi-alkylated species and is free from dicyclopentadiene and mixed dicyclopentadiene species.

Furthermore, the patent also outlines an alternative process for preparing the compound of Formula (I) with similar requirements for protic reagents and composition specifications. The use of water, alcohol, or polyol in conjunction with acids is emphasized in this process as well. The patent highlights the importance of specific R1 and R2 groups, such as methyl, and the choice of C1-C8 alcohols for optimal results. Overall, the patent provides detailed methods for the preparation of the compound of Formula (I) while maintaining strict criteria for its composition and purity.
